** Violent storms in autumn appeared like a punishment. This was also the season, in ancient China, to perform executions of criminals sentenced to capital punishment. Wang Bing: When the mental Qi is hectic, one is not careful in their activities. If one is not careful in their activities, one accentuate the severity of autumn punishments, goes along with killing, and destroys life. Hence, one establishes a peaceful and tranquil mind to soften the punishments carried out in autumn.

*** Wang Bing: It is to say: to carry out the orders of summer in contrast [to the requirements of autumn]. The lung corresponds to metal and flourishes in autumn. Hence, to carry out [in autumn] the orders of summer, this harms the Qi. In winter the water flourishes and the metal perishes. Hence, the disease develops in winter. If one opposes the [orders of] autumn and harms the lung, this results in diminished Qi [with a reduced ability] to receive the storage in winter.
